Composite Electrodes for Ultracapacitors

Introducing the Nanoramic CE, Composite Electrodes for Batteries and Ultracapacitors

learn more

The Nanoramic Composite Electrode (CE) is an electrode for EDLCs and Li-Capacitors.
This is a binderless electrode that is composed of 100% high purity carbon.


Ultra low ESR
High stability at high temperature
Excellent capacitance and ESR retention in harsh conditions
Compatible with standard stacking and winding processes
Lower ESR and Capacitance variation at low temperature
Designed and Assembled in the USA


Nanoramic’s nanocomposite technology was originally developed by FastCAP systems Corporation to meet energy storage needs inthe extreme environments encountered in geothermal drilling.  Today, Nanoramic has leveraged this technology to introduce Nanoramic CE.

Nanoramic CE is an advanced electrode solution that is compatible with most widely used electrolytes, and can be used as a “drop in” replacement to existing energy storage device designs to radically improve the performance of the device.

Nanoramic CE can be used to increase one or more of the operating voltage, temperature rating, and lifetime of existing devices, pushing them to new levels of performance

As clearly shown, the Nanoramic CE enables operation at high temperature while keeping high voltage with off-the-shelf electrolyte, which the incumbent cell quickly fails. At a given capacitance, the ESR is less than half of incumbent wound cells.
